Don't google "Wouxan KG-1000" then
This. And even if you can overcome this relatively small barrier yourself, the majority of people waiting to talk to you on are ham people with ham hobbies, not Jeep guys. So you are back to the question of do you want to do this to get into radios, or do you want to be able to communicate with people on the trail (plus a little radio nerding if you want to boot).
GMRS has much better clarity, better range on simplex (atmospheric skips aside), and the ability to utilize repeaters, so it trumps CB easily. And the bar to play is much lower than ham which means easier plus more novice non-radio type people to have the ability to talk to. Sure, ham is "better," but to what end? What do you actually plan to do with your new found comms?
I get it. I’m just bummed that my two new worlds (Ham and Jeep) are requiring me to duplicate time, energy, money, and equipment for no actual benefit. But again, that’s my problem. My original question of “why GMRS when we already have Ham?” has been answered, and although I don’t like the answer, it’ll be much easier to get a GMRS setup than to convince all other Jeepers to go to Ham.
